Sketch Diagram
A floor plan is the most fundamental architectural diagram, a view from above showing the arrangement of spaces in, showing the arrangement at a particular level of a building. Technically it is a horizontal section cut through a building (conventionally at four feet / 1200mm/1.2 m above floor level), showing walls, windows and door openings and other features at that level. The plan view includes anything that could be seen below that level: the floor, stairs (but only up to the plan level), fittings and sometimes furniture.

Landscape master plan
An elevation is a view of a building seen from one side, a flat representation of one facade. This is the most common view used to describe the external appearance of a building. Each elevation is labelled in relation to the compass direction it faces, e.g. the north elevation of a building is the side that most closely faces north

A cross section, also simply called a section, represents a vertical plane cut through the object, in the same way as a floor plan is a horizontal section viewed from the top. In the section view, everything cut by the section plane is shown as a bold line, often with a solid fill to show objects that are cut through, and anything seen beyond generally shown in a thinner line
Cross section/Section
Isometric (30 deg) and axonometric (45 deg) projections are a simple way of representing a three dimensional object, keeping the elements to scale and showing the relationship between several sides of the same object, so that the complexities of a shape can be clearly understood
Isometric and axonometric
Perspective in drawing is an approximate representation on a flat surface of an image as it is perceived by the eye. Perspective is the view from a particular fixed viewpoint
Perspective
A sketch is a rapidly executed freehand drawing, a quick way to record and develop an idea, not intended as a finished work. A diagram may also be drawn freehand but deals with symbols, to develop the logic of a design. Both may be worked up into a more presentable form and used to communicate the principles of a design
